See the above URLs for further information. I have to say that we do not use it that way, and I cannot recommend such a strategy. (We're the ones using it for .org and .info.) Failing over is something of a pain in the neck, and it is not 100% reliable in cases where you have flakey hardware (as I learned to my chagrin recently). That said, the replication itself has not failed for us. PostgreSQL, Inc. sells a version which is somehow linked to a Linux system; I don't know very much about it, so it may work perfectly well. But that is _not_ the system we are using. There are some other replication systems, as well, but I have no experience with them. For more information on replication, see Bruce Momjian's recent presentation on it http://candle.pha.pa.us/main/writings/pgsql/replication.pdf or visit the replication gborg site http://gborg.postgresql.org/project/pgreplication/projdisplay.php We are very happy with PostgreSQL, and have consistently good experience with its reliability and speed. I would strongly recommend it, with one of the various replication systems.
